Adaptive Air Suspension
Air suspension and damping
Applies to vehicles: with Adaptive A ir Suspens ion
Description
Air suspension and damping can be regulated as desired
by driver, and they adapt automatically to the driving situ
ation at the time.
Adaptive Air Suspension is an electronica lly contro lled springing
and damping system. This chassis system makes it easier on the
driver by adapting to the particular situation through imperceptible
control processes.
The
Adaptive Air Suspension component regulates ground clear
ance depending on vehic le speed and driver inpu t. It functions inde
pendently from the load condition. Accelerating to a speed above a
predetermined limit will make the vehic le lower itself . On the other
hand, driving more slowly results in the vehicle raising again at
specific speeds.
The
damping component provides individual control of the
damping forces. For example, with damping characteristics set to
provide greater comfort, damping is set somewhat harder for a brief
period only as required, for example, when going around a curve or
when braking.
Settings
Adaptive Air Suspension prov ides the driver with the opportunity to
set the chassis characteristics a lso to their individual preference.
With the driving modes
comfort, automatic and dynamic the driver
has three chassis settings available, ranging from comfort to sporty.
The
offroad mode can be selected for driving on poor qua lity
stretches of road. In addition, lift provides a fifth mode, which can
be selected when exceptionally high ground clearance is needed
=> page 207, "Chassis controls". The modes are set in
MMI:::::,
page 208.
& WARNING
The height of the parked vehicle can change due to temperature
fluctuations or changes in load.
0 Note
• Whenever you park your vehicle, always make sure there is
adequate clearance above and below the vehic le. The height of the
parked vehicle can change as the result of temperature fluctuations,
changes in load condition and changes in the driving mode (ground
clearance!.
• If the vehicle is being transported (e.g. by tow truck, train, ship,
etc.), mount the tie -down chains/cables over the running surface
(circumference) of the tires . Never secure the veh icle by the axle, the
suspension struts or the front or rear towline eye. For technical
reasons, the pressure in the suspension struts may change during
the transport, which could result in the vehic le no longer being
secured properly.
• If you are going to tow a trailer with a trailer hitch that was
not
installed according to factory specifications, you must activate the
trailer operation mode manually:::::,
page 211.
[ i ] Tips
• Before you can raise your vehic le using the vehicle jack (for
example, when changing a flat tire) or a vehicle lift, you must acti
vate the jacking mode:::::,
page 210.
• On some models, the vehicle can reach its maximum speed only
in the
automatic and dynamic modes. •

Repeated, brief tapping of the [R ESET] button on the windshield
wiper lever allows you to select whether information concerning the
trip computer, digital tachometer , navigation* or "Adaptive Air
Suspension" is to appear in the instrument c lu ste r disp lay.
Disp lay of the Adapt ive Air Suspension is automatic when the
off road or lift mode is sel ected, or when the v ehicle is automatically
lowered in lif t mode .
Raising and low ering
If arrow G) is solid red=> page 209, fig. 226 or white => fig. 227, the
vehic le is raised .
If ar row
0 is solid red or white, the vehicle is lowered .
The respective arrow stays on unti l the leve l change is complete.
The time required for a leve l change can vary, depend ing on the
current driv ing cond it ions .
Displ aying the vehicle level
The current vehicle level is shown with segments filled out in the
segment display@. If only the bottom segment is filled out, the
veh ic le is at highway level. If al l segments are filled out, the vehicle
is at high level 2 and has the grea test amount of ground c learance
possible .
Whi le the veh icle is being raised or lowered, the target level is indi
cated by an arrow© nex t to the co rresponding segment . The arrow
d isappears again when the vehic le is at the targe t level. •

& WARNING (continued)
• Loose items in the passenger compartment can cause serious
personal injury during hard braking or in an accident .
- Never store the inflatable spare tire or jack and tools in the
passenger compartment.
- Always store all jacking equipment, tools, and the inflatable
spare tire in the luggage compartment.
- Tighten the knurled retaining screw for the inflatable spare
tire securely.
0 Note
• Th e inflatable spare tire has been developed specifically for this
vehicle model. It must not be exchanged or used for other vehicle
models. Similarly, inflatable tires from other vehicle models must
not be used.
• Normal summer or winter tires must not be installed on the
inflatable tire rim.•
Changing a wheel
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing a wheel.
-After you experience a tire failure, pull the car well away
from moving traffic and try to reach
level ground before
you stop => & .
- All passengers should
leave the car and move to a safe
location (for instance, behind the guardrail)=> &.
- Engage the
parking brake to prevent your vehicle from
rolling unintentionally=> &. -
Move
selector lever to position P =:> & .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Block the diagonally opposite wheel with the folding
chocks or other objects.
- Take the
jack and the inflatable spare tire out of the
luggage compartment=>
page 370.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flashers on and use other warning
devices to alert other motorists.
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack , always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed with the
folding chocks or other objects. When one front wheel is lifted off
the ground, placing the Automatic Transmission in "P" (Park) will
not prevent the vehicle from moving.
• Before you change a wheel, be sure the ground is level and firm .
If necessary, use a sturdy board under the jack.
• After installing the inflatable spare tire, make sure that you
replace the flat tire/wheel in its storage area properly and tighten
the knurled retaining screw securely. •
